SPINNING 0R WINDING- MACHINE.

T 0 all 107mm t may Concern:

Be it known that I, WILLIAM E. VVALsH, a citizen of the United States, residing at Lowell, in the county of Middlesex and State of Massachusetts, have invented an Improvement in Spinning or Winding Machines, of which the following description, in connection with the accompanying drawings, is a specification, like characters on the drawings representing like parts.

The invention to be hereinafter described relates to spinning or windin machines, and' more particularly to the bui der mechanism for winding yarn on the receivers or bobbins to be subsequently used asl the lling or weft, during kthe weaving of cloth.V

In looms of the feeler type, wherein the filling is replenished prior to complete exhaustion, it is usual to provide a reserve supply' of filling on the bobbins or other receivers, to prevent partial or mispicks after a call Jfor replenishment. Many devices have been devised for placing this reserve supply of filling or bunch as it is sometimes called, on the bobbins or receivers during the spinning operation; and Vone of the objects of the present invention is to provide a mechanism othis general character which shall be simple in construction and effective in operation.v Y Economic reasons dictate that the reserve supply of filling remaining on the bobbin or receiver when it is ejected and a new' supply is furnished, shall be as small as possible consistent with proper regard or mispicks or partial picks and tension of filling. One of the purposes of the present invention, therefore, is to provide a mechanism which will place upon the bobbins or Yreceivers, reserve supply of filling or primary windings, as they may be called, which shall be suiiicientin 'amount to prevent partial or mispicks, and furnish suflicient ten sion, and yet shall cause minimum waste when the bobbins or receivers are ejected from the loom.

IVhen the bobbins or receivers are of the slotted type for the entrance of the feeler when the filling'has been substantially exhausted, it is desirable that the reserve supply of illing or primary windings may be Specification of Letters Patent.

located at or beyond one end of the slot in the bobbins or receivers, and that such slot may be co-vered by suliicient windings of yarn or thread to prevent entrance of the feeler or actuation of the replenishing mech'- anism until the filling has reached the d esired state of exhaustion. A n important feature of the present invention, therefore, consists in means for lacing at one end of the slot of such slottedO bobbins or receivers, the reserve vsupply of filling, and to cover the slot by a service winding which is placed upon the bobbins or receivers immediately uponthe completion of the reserve supply or primary windings. In carryin this feature of the invention into effect, t e reserve supply or preliminary windings are preferably placed adjacent the base or head of the bobbins or receivers by an upward and ay downward short traverse of the yarn or thread, and then a full service traverse to cover the slot in the bobbins or receivers.

The invention will be described in connection with a worsted spinning machine, but' it is to be understood that it is not limited thereto, and may be adapted for use in any character of spinning or winding machines.

In the drawings:

Fig. 7 is a similar view, showing the relarail of theA worsted spinning machine.:

Mounted on the spindle-rail 3 are a series of spindles 4 of any yappropriate number,l which extendvupwardly through a way-plate or lifting rail 5. Each of the'spi'ndles 4 is adapted to support the yarn receiver or bobbin @which extends upwardly into the caps 7, (Fig. 1) mounted as usual upon the top portion of the respective spindles 4 or p supported in any other desired or suitable manner, the lower edge portion of the cap 7 constituting yarn guides for directing the yarn to the bobloins` or receivers.` As usual in worsted spinning machines, the bobbins are suitably rotated for spinning and winding the yarn. y y

Suitably mountedon the machine frame is the'cam shaft '8 having secured thereto for rotative movement the cam 9 which shall constitute the usual builder cam.

Pivotally mounted on the machine frame at 10 is the swinging arm y11l carrying the roller 12 which bears upon the cam 9. PivotallyV moiuited at the lower portion of the machine 'f as at13', is the :arm 14Y which may be of the usual construction, and on the arm 14 is the bracket 15 carrying the roller 16 which bears upon the plate face 17 of the swinging arm 11,-whereby the swinging movement of the arm 11 maybe transmitted `to the arm 14. The bracket 15 has connected 4thereto the rack 18 which engages a pinion 19 connected to the rotating shaft 20, the latter being o-perated' as usual in this class of machines,

-. from suitable power through the train of gearing 21, 22. Connected to the shaft 20 and the arm 14 is the traverse screw 23 which transmits traverse motion from thecam-operated swinging arm 11 to the traverse slide 24 during the service ,traversa The parts thus far described may be of usual construction `employed in worsted spinning machines, and since they are well understood by those skilled in the art, further detailed description thereof is unnecessary.

The traverse rod 24 has connected thereto the chaintofother flexible connection 25 securedttothe projection 264at the lower portion of the lifter rods27, the upper vends of y the latter. beingv connected to the way plate lor lifter rail 5, the construction being such that traverse movement imparted to the traverse rod 24 is transmitted to the way-plate 5 to raise and lower the same.v The chain or connection 25 between the traverse rod and projections 26 may be suitably guided upon guide rolls 28, 2 9, Fig; 1.KVA u n Y Mounted upon the traverse vrod 24.is an auxiliary cam 30, the function of which is to impart to thetraverse rod suitable short traverse movements to lay; upon the filling carriers or bobbins the primary windings. In the present instance, the traverse rod 24 ha'ssecur'ed theretol a bracket 31, Figs. 4 and 5, which is provided with a bearing 32 through which extends thej auxiliary caml shaft 33"- The auxiliary cam'30, in the *preisproperly guided' under'the weight 'of the parts carried thereby as Vwill* more fully appear, the spindle'frail 3 has secured thereto a bracket 35', Fig. 1, the lower end portion of which is provided with slotted'guide 36,.'`

Figs. 1 and 5, through which thecamshaft 33 extends, the' construction being such that' the slotted guide bracket-serves to supportv and guide the traverse rod 24'in its movements.

Lo-osely mounted on the' cam' shaft'33 is a sprocket wheell 37 about which passes the sprocket chain 38. The sprocket chain 38 may be driven from any suitable sourceV of power, but in the present instance of the invention it is connectedfto a Vsprocket wheel 39v secured to the shaft 8 said chain passing about, suitable guide pulleys 40 and`41 projecting' from `a bracket 42 extending downwardly from the longitudinaflrail 2, Fig. 1, the vconstruction being such that during the operation of the machine, the sprocket wheels 39 and 37 will be" continuously rotated.

Secured to the cam shaft' 33 is an arm 43 carrying ahand' piece 44 and a spring-actuated locking pin 45, Fig.V 5, which is adapted't'o engage anyone of a series of openingsv V ent instanceof the'invention, is secure-dr to builder cam 9 andthe auxiliary cam30'vvill be continuously operated.

The locking pin 45 may be variously contrived', but in the presentV instance' of the invention, it comprises the pin 45' extending through the liandpiece and having a collar147, Fig.l 5', between which and an adjustable stop 47 is interposed afspring 48 norn.

mally acting tol move the pin' 45' into locking engageinent with one' of the openings 46 Y upward and then in 4a. downward direction y ofthe sprocket wheel 37. The' outer end portionk of thepin 45 isv providedl with a hand-piece 49, whereby thepin 45 may beV wheel 37 when' ings at the baselof the bobbin or adjacent the head thereof, and upon completion of one or more -short traverses,`to pass at once to the service or long traverse. 'To this end there is provided a datum stop which determines the traverse of the preliminary windings in an upward direction from the base lof the bobbin, and upon completion .of one or more of such short'or preliminary traverse windings, is automatically moved tov an inoperative position to permit service windings or long traverse to be resumed. In the present instance of the invention', the datum stop consists of an yarm 54,. Fig. l, adj ustably mounted in a sleeve 55 pivotallyxmounted on a bracket 56 at 57 and held in adj usted-position in the sleeve 55 by suitable means such v as the nuts 58. The 'arm 54 carries the stop proper 59, the toe portion 60 of which is adapted to engage the enlarged portion 61 of the plunger or movable member 52 and prevent movement of the plunger to the left, Fig. l, during the actionv of the vauxiliary cam 30, the construction being such that' during the. action of the auxiliary cam 30, the traverse rod 24 which carries the cam, will be moved under the dictates of the auxiliary cam to lay the preliminary windings from the base of the bobbin upwardly to the datum point determined by the datum stop,

Vand then downwardly to the base of the bobbin and upwardly again, the traverses during the actionof the auxiliary cam r3() being relatively short. When the preliminary windings have been thus laid first in an to .furnish .the desired reserve filling, it is desirable that full service traverse shall be at once resumed and the present invention provides means to this end, as will now be described.

The 54 of the datum stop connected thereto a iexible member or cord 62, Fig.

l, which passes'about suitable guide rolls 63 and has secured thereto a weight 64. Between the weight and the cord 62 is interposed a plate 65V which passes through a slot 67 in 'a'platel 68 and is provided with a pin 66 which normally rests uponfthe plate 68 above the slot. f The slot -67 has an enlar ed portion 69, Fig. 2, which, when brought elow the pin 66, permits the weight 64 to lift the datum stop from its operative position.

The plate 68 as'indicated in Fig. l, is slidably mounted in suitable ways or guides 70 secured to the rail 2, and is provided with' a series of ratchet teeth 7l adapted to be eneVV gaged by a pawl 72 carried by the swinging l arm` 11, ythe construction being such that during the rotative movement of the cam 9 on the shaft 8, the swinging arm 1l and the pawl 72 will be actuated to feed the plate 68 to the right, Fig. l, and finally bring the enlarged opening 69 of the plate below the pin 66 `to permit the latter. to pass, and the datum stop to be raised from operative position. The above-described means constitutes a good form of mechanism for the purposes of automatically controlling the time of movement of the datum stop from its operative to its inoperative position, but obviously this means may 'be variouslv contrived.

When the datum stop is removed from its operative position, it is desirable that the plunger or movable member 52 be locked to the traverse rod, and various forms of mechanism may suggest themselves for this purpose, but in the present instance of the invention a plate 73- is hinged at 74 to the guide 5l in which the plunger 52 is supported, and said plate 73 is normally under the influence of a spring 75 tending to lift the plate into the position indicated in Fig. 6.

` Secured to the free end portion of the plate 73 bymeans such as the screw' 76, is a leaf Vspring 77. rRising from the guide 51 are overpowering the spring 75, so that when the 1 plate 73 is free to be moved downwardly, under the impulse of the spring 77, it will respond thereto. Secured to the rock shaft 7 9 1s an'operating member or arm 82 which 1s -adapted to engage a stop 83 secured to the plunger 52, the construction being such vthat'when the parts are in the position indicatedin Fig. l, and the 'traverse rod 24vis p moved to the left by the auxiliary cam 30 in laying the first short` preliminary wind-l ings, theend portion of the plate 73 previously resting upon the stop 61of the plunger would take the position as indicated in Fig. 7 thereupon locking ythe plunger to the f traverse rod 24 or preventing movement of the plunger 52 tothe, right relativev tothe.

dicated in Fig. 7, and therefrom, further rotation ofV the auxiliary cam 30 has no ef'- feet upon the traverse rod, the head of the plunger 52 resting against the end of the traverse screw 23, andiull or-service traverse vwill thereupon be initiated.

In commencingy the operation oi'fV winding I the -yarn upon the bobbins orcarriers, the;v

attendant, by means of the hand-piecel 44 and locking device carried thereby, turns the cam-shaft to position. the auxiliary cam 30 as indicated in Fig. 1, and then locks the cam to the sprocket wheel 37. l1-hedatum stop is then vmoved-to operative position by hand, and the plate- 68= adjusted to support the weight 64. The rock shaft 79 is then; turned into the position indicated` in Fig. l, the parts related as shown in said figure being then yin starting position. Asthe auxiliary cam 30 is rotated' through the describedmeans, it acts upon the plunger 52 and moves the traverse rod 24 to the left, therebyl traversing the yarn by short traverses upwardly from thebase ofthebobbin; and.` when the cam has reached the positionindi cated in Fig;l 6, having made a half-turn, the arm 82 will have engaged the stop 83 on the plunger and turned the finger 81 from the position indicated in Fig. 1 to that indicated in Fig. 6, thereby placingthe leaf yspring 77 under tension. When the cam 30 moves from the position indicated in F1g.f6'

to tha-t indicated in Fig. 7 it moves the traverse rod 24 to the right, Fig.5 1, Vthereby traversing the yarn downwardly fromv the datum point fixed by the stop, and the-.plate 73' locks the plunger 7 2 through the traverse rod, the end of the plunger 52 atfsucli time resting against thetraverse. screw 23; Anyl further rotation oi the auxiliary cam 30 ob viously has no further effect, and service traverse at once continues upwardly toA cover the slot in the bobbins by thev service windi ings.VV v

Infthepresent instance of the invention,

the auxiliary cam 80 imparts short traverse to the yarny from a point adjacent the head of the bobbin upwardly to the datum point, and

then downwardly, at which time the. auxiliary cam has made one complete revolution,

Yand thereupon full service windings are resumed by theusual builder cam and swingingfarm. What is claimed is 1. In a machine of the class described, thev combination of the series of spindles, co-
